To (ZZZ whmn it may concern:

Be it known that I, ERNEST S. DE Von, a citizen of the United States, residing at'Allenwood, in the county of Monmouth and State of New Jersey, have invented new and useful Improvements in Railway-Sleepers, of which the following is a specification.

This invention is a metallic railroad-tie of the box-beam type, and it is characterized by improvements with respect to the construction of the tie itself and also with respect to the means for attaching the rail thereto.

In the accompanying drawings, Figure 1 is a top plan view of the tie. Fig. 2 is a side View. Fig. 3 is a plan view of the blank from which the ends of the tie are formed. Fig. I is a detail in section, illustrating the fastening means for the rail. Fig. 5 is an end view.

The tie is constructed of several plates riveted together in box form. The top and bottom plates are indicated at 6, riveted, as at 7, to the flanges 8 of the channel-plates 9, forming the sides. The lines of rivets extend along the edges and are preferably countersunk on both sides. Into the box thus formed are fitted ends 10, (shown in the blank in Fig. 3,) which is bent on the lines 10 to produce a box-like form which fits snugly within the main beam. These end plates serve to strengthen the tie and to exclude dirt and the like therefrom.

As a means for attaching the rails to the tie in a manner which will be secure, but which will also permit rapid change when desired, I use a clip-plate 11, which is riveted at 12 to the top plate of the beam and projects at the other end over the base of the rail. This clip carries a-projecting pivot or stud 13, which is en-gageable in the hole in a keeper 14, which laps over the clip and which is pivoted to the top plate of the tie by a rivet at 15. Four of these clips or fastening T0 atdevices are used, two for each rail.

tach or detach the rail, the keeper-plate let is sprung up until the stud 13 will pass out of the hole therein. The clipll may then be hammered around on its pivot 12 to release the base of the rail. To attach the same again, it is simply necessary to knock the clip back and allow the keeper to spring down thereon with the stud 13 in the hole therein. This arrangement holds the rails securely, while at the same time permitting quick removal. There are no bolts having nuts to come off or work loose, the danger of which is thus obviated.

The ties are held in position in the ground by their weight and also by the engagement in the ground of the flanges 8 on the side plates of the tie.

What I claim as new, and desire to secure by Letters Patent, is

1. A railroad tie comprising upper and lower plates, side plates having outwardlyprojecting flanges to which the upper and lower plates are secured, and flanged end plates fitting in the ends of the tie and bolted to said plates.

2. The combination with a metallic tie, of a rail-clip pivoted thereto, and a keeper-plate secured to the tie and having detachable engagement with the clip.

3. The combination with a metallic tie, of a rail-clip secured at one end thereto by a rivet acting as a pivot having a projection on the upper side, and a spring-plate secured to the tie and having an opening into which said projection extends.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ERNEST S. DE VOE.
